Inflammatory bowel disease induces pathological α-synuclein aggregation in the human gut and brain.

AIMS: According to Braak's hypothesis, it is plausible that Parkinson's disease (PD) originates in the enteric nervous system (ENS) and spreads to the brain through the vagus nerve. In this work, we studied whether inflammatory bowel diseases (IBDs) in humans can progress with the emergence of pathogenic α-synuclein (α-syn) in the gastrointestinal tract and midbrain dopaminergic neurons. METHODS: We have analysed the gut and the ventral midbrain from subjects previously diagnosed with IBD and form a DSS-based rat model of gut inflammation in terms of α-syn pathology. RESULTS: Our data support the existence of pathogenic α-syn in both the gut and the brain, thus reinforcing the potential role of the ENS as a contributing factor in PD aetiology. Additionally, we have analysed the effect of a DSS-based rat model of gut inflammation to demonstrate (i) the appearance of P-α-syn inclusions in both Auerbach's and Meissner's plexuses (gut), (ii) an increase in α-syn expression in the ventral mesencephalon (brain) and (iii) the degeneration of nigral dopaminergic neurons, which all are considered classical hallmarks in PD. CONCLUSION: These results strongly support the plausibility of Braak's hypothesis and emphasise the significance of peripheral inflammation and the gut-brain axis in initiating α-syn aggregation and transport to the substantia nigra, resulting in neurodegeneration.

Salmonella Control in Swine: A Thoughtful Discussion of the Pre- and Post-Harvest Control Approaches in Industrialized Countries.

Pork is among the major sources of human salmonellosis in developed countries. Since the 1990s, different surveys and cross-sectional studies, both national and international (i.e., the baseline studies performed in the European Union), have revealed and confirmed the widespread non-typhoidal Salmonella serotypes in pigs. A number of countries have implemented control programs with different approaches and degrees of success. The efforts could be implemented either at farms, in post-harvest stages, or both. The current review revises the current state of the art in Salmonella in swine, the control programs ongoing or conducted in the past, and their strengths and failures, with particular attention to the weight of pre- and post-harvest control and the implications that both have for the success of interventions or mitigation after outbreaks. This review provides a novel perspective on Salmonella control in swine, a matter that still includes uncertainties and room for improvement as a question of public health and One Health.

New insights into swine dysentery: faecal shedding, macro and microscopic lesions and biomarkers in early and acute stages of Brachyspira hyodysenteriae infection.

BACKGROUND: Swine dysentery (SD) is a severe mucohaemorrhagic colitis in pigs caused classically by Brachyspira hyodysenteriae. Although several aspects of B. hyodysenteriae infection dynamic are already described, further research in the early stage of this infection is required. In this study, 7-week-old pigs were orally challenged with B. hyodysenteriae to obtain information about faecal shedding, macro and microscopic intestinal lesions and serum acute phase proteins in pigs at the onset of B. hyodysenteriae shedding (early infection group, n = 8), in pigs with mucohaemorrhagic diarrhoea (acute infection group, n = 8) and in non-infected controls (n = 16). RESULTS: First B. hyodysenteriae detection by q-PCR and first loose stools with blood and mucus occurred both at 8 days post-inoculation. The lapse between a positive q-PCR and observation of mucohaemorrhagic diarrhoea ranged from 0 to 3 days, except in a single pig in which this period lasted 5 days. Macroscopic lesions were observed in the large intestine from both infected groups although more frequent and severe in acute infection group. Microscopic observation of the apex mucosa revealed that in early infection only higher ulceration values were observed compared to healthy controls. In contrast, the acute infection group exhibited higher ulceration, neutrophils infiltration and increased mucosal thickness compared to the other two groups. Among the serum biomarkers tested, only haptoglobin, C-reactive protein, and creatine kinase showed a significant increase in pigs in the acute infection period compared to controls, whereas haptoglobin was the only factor with a significant increase at the early infection compared to non-infected animals. CONCLUSIONS: This study provides new insights about SD and remarks the complex and limited options to perform an early detection of infected animals beyond PCR diagnosis.

Valorization of Saithe (Pollachius virens) Residuals into Protein Hydrolysates-Silaging as Preservation Technology.

Silaging can be used as preservation technology to valorize currently discarded raw material into protein hydrolysate on board deep-sea vessels. The aim of this study was to investigate the effect of sorting and raw material freshness on the quality and yield of protein hydrolysates obtained through silaging of saithe (Pollachius virens) viscera. Additionally, the effect of using acid-containing antioxidants was tested. Out sorting of the liver prior to silaging resulted in slightly higher hydrolysate yields. The hydrolysates with the highest protein contents were obtained from silages made from fresh raw materials (day 0), and the content decreased significantly after longer storage of the raw material (2-3 days at 4 °C). Storage of the raw material for 1 day did not affect the quality. However, a significantly higher degree of hydrolysis (DH), content of free amino acids (FAA), and total volatile basic nitrogen (TVB-N) were obtained when raw materials were stored for 3 days. The FAA composition was influenced by the raw material's freshness, with increases in free glutamic acid and lysine and a decrease in free glutamine after longer storage. None of the studied parameters were significantly affected by out sorting of liver or the addition of antioxidants. Overall, the results indicate that the whole fraction of the viscera can be utilized without reducing the quality of the hydrolysate and that the raw material should be stored for a maximum of 1 day prior to preservation to optimize the quality.

[Dietary diversity, anthropometric status and biochemical profile of centenarians of the Nicoya Peninsula, Costa Rica, and their offspring]. / Diversidad dietética, estado antropométrico y perfil bioquímico de centenarios de la Península de Nicoya, Costa Rica, y su descendencia.

BACKGROUND AND OBJECTIVE: Social relationships, physical activity and diet have been proposed as responsible for longevity; however, many of these conditions have changed in modern societies. The objective of this study was to identify if the anthropometric status, biochemical profile and diet of Nicoyan centenarians is different from that of their decency and if the quality and diversity of the diet of these Costa Ricans differs from that of adults from urban areas of the same country. MATERIALS AND METHODS: Anthropometric, biochemical and dietary assessments were carried out on 120 adults residing in the Nicoya Peninsula, including centenarians, their children and grandchildren. The data were analyzed using descriptive and inferential statistics. RESULTS: There is a significantly lower percentage of excess weight, central adiposity and blood lipids in Nicoyan centenarians compared to their children and grandchildren. The consumption of «Dairy¼ and «Other fruits¼ is higher in centenarians than in their descendants. Centenarians showed a higher dietary diversity index (DDI) compared to other age categories, and they also showed a higher DDI and a significantly more diverse diet than the urban population of Costa Rica. CONCLUSION: Nicoyan centenarians presented a better lipid and glycemic profile than their offspring, they have lower weight and a better quality and diversity of diet than their relatives and than adults from the urban area of Costa Rica.

Exploring the Potential of Atlantic Mesopelagic Species Processed on Board Commercial Fishing Vessels as a Source of Dietary Lipids.

This study investigates the use of untapped mesopelagic species as a source of long-chain polyunsaturated omega-3 fatty acids (LC n-3 PUFAs) to meet the growing demand. The challenges faced by commercial fishing vessels, such as varying catch rates and species distribution affecting lipid levels, are addressed. Marine oils were produced post-catch using thermal separation and enzymatic hydrolysis during four commercial cruises, screening approximately 20,000 kg of mixed mesopelagic species. Maurolicus muelleri and Benthosema glaciale were the dominant species in the catch, while krill was the primary bycatch. The lipid composition varied, with B. glaciale having a higher prevalence of wax esters, while triacylglycerols and phospholipids were more predominant in the other species. LC n-3 PUFAs ranged from 19% to 44% of lipids, with an average EPA + DHA content of 202 mg/g of oil. Both processing methods achieved oil recoveries of over 90%. Estimates indicate that the mesopelagic biomass in the Northeast Atlantic could supply annual recommended levels of EPA + DHA to 1.5 million people, promoting healthy heart and brain functions. These findings offer valuable insights for considering mesopelagic species as a potential source of dietary marine lipids, laying the groundwork for further research and innovation in processing and obtaining valuable compounds from such species.

Salivary Cortisol Levels after Hydrotherapy and Land-Based Therapy as a Marker of Stress in Children with Psychomotor Developmental Disorders: A Pilot Study.

Background: The number of children experiencing postnatal situations of neurological risk (such as psycho-motor developmental disorders and delays) after birth has increased in recent years. These infants often require multiple pediatric interventions to address functional problems that might generate stress, anxiety, and discomfort. The aim of the present study is to determine whether the level of salivary cortisol, as a stress marker, increases after hydrotherapy and land-based therapy in children at risk of or currently presenting delayed psycho-motor development. Methods: Saliva samples were collected from 25 children (aged 3-36 months) between June 2022 and January 2023 at the Rehabilitation and Physical Medicine Clinical Management Unit of the Virgen de las Nieves University Hospital, Granada, Spain. Three samples were collected from each child, representing baseline, post-hydrotherapy and post-land-based therapy. Result: All salivary cortisol levels were within the normal range. Resting values were the highest, and both modes of therapy decreased salivary cortisol levels. There were no statistically significant differences between the two therapies. Conclusions: Both therapies appear to be useful for treating children with psychomotor developmental disorders without increasing stress during physiotherapy sessions. Although cortisol levels were slightly higher with hydrotherapy than with land-based therapy, this may be due to the small sample size.

[Review of nutrition and hydration in relation to physical exercise during pregnancy]. / Revisión de la nutrición e hidratación con relación al ejercicio físico en el embarazo.

Studies on nutritional recommendations for pregnant women who exercise are scarce. The objective of this article is not to focus on the diet of pregnant women as a whole, but to review those aspects of it that may be related to physical exercise. To this end, the nutritional and hydration recommendations contained in the main clinical practice guides on physical exercise during pregnancy are collected, including the first Spanish guides. Likewise, the energy requirements required by pregnant women who perform physical exercise during pregnancy for adequate gestational weight gain are addressed, aspects related to macronutrients in the aforementioned population group, and two specific topics, such as nutritional needs in the adolescent who practices physical exercise during pregnancy and eating disorders in pregnant athletes It is concluded by stating that pregnant women who exercise regularly should eat a varied and balanced diet, such as the Mediterranean diet, avoid long periods of fasting to avoid the appearance of hypoglycemia and maintain adequate fluid intake before, during and after physical exercise. Pregnant adolescents who engage in physical exercise require nutritional supervision to achieve adequate gestational weight gain. The pregnant athlete with an eating disorder has a higher risk of complications during pregnancy and childbirth, gynecological, fetal and neonatal, and, therefore, requires close monitoring by specialists in maternal-fetal medicine.

Experiencia piloto en atención primaria: intervención de terapia ocupacional en el contexto natural / Pilot experience in primary care: occupational therapy intervention in a natural context

Introducción: tanto la terapia ocupacional como la atención primaria centran sus intervenciones en las necesidades y preferencias individuales de la persona, y establecen una estrecha colaboración con ésta y con su entorno. Dentro del sistema sanitario público andaluz se contempla la figura de la terapia ocupacional en los dispositivos de apoyo, pero no está clara su estructura asistencial. El objetivo de este trabajo es profundizar en la necesidad e importancia de la figura de la terapia ocupacional en niveles asistenciales primarios. Métodos: durante el mes de octubre de 2021, cinco terapeutas ocupacionales contratados por el Distrito Sanitario Granada-Metropolitano para funciones de rastreo COVID-19, llevamos a cabo un trabajo externo relacionado con funciones propias de la disciplina en cinco centros de salud de la provincia. Recogimos datos a través de la Medida Canadiense del Desempeño Ocupacional y de una encuesta de elaboración propia. Conclusión: existe una base teórica muy amplia que sustenta los beneficios que puede aportar la terapia ocupacional a la atención primaria. La combinación entre ambas puede ayudar al sistema sanitario público andaluz a mejorar resultados en prevención, rehabilitación y reducción de costes.(AU)

Introduction: Both Occupational Therapy and primary care focus their interventions on the client’s individual needs and preferences and establish close collaboration with them and their environment. Within the Andalusian public health system, Occupational Therapy is included in the support devices, but the care structure is not clear. The aim of this study is to explore the need and importance of Occupational Therapy at the primary care level. Methods: During 2021 October, five occupational therapists contracted by the Granada-Metropolitan Health District for COVID-19 follow-up functions carried out external work related to the discipline’s own functions in five health centers in the province. Data were collected through the Canadian Occupational Performance Measure and a self-developed survey. Conclusion: There is a board theoretical basis for the benefits that Occupational Therapy can bring to primary care. The combination can help the Andalusian public health system to improve outcomes in prevention, rehabilitation and cost reduction.(AU)

Hipospadias: del diagnóstico ecográfico prenatal al manejo posnatal / Hypospadias: from prenatal ultrasound diagnosis to postnatal management

El hipospadias es la localización anormal del meato urinario y es la malformación de genitales externos más frecuentemente diagnosticada. El diagnóstico prenatal es posible mediante ecografía sistemática desde la semana 20 de gestación, siendo más fácil su diagnóstico en el tercer trimestre. Las formas leves suelen ser aisladas, familiares o asociadas a disfunción placentaria o restricción de crecimiento intrauterino, mientras que las formas más graves presentan hasta un 30% de asociación a defectos fetales, anomalías cromosómicas/genéticas o anomalías del desarrollo sexual. La tríada para el diagnóstico ecográfico prenatal consiste en curvatura ventral del pene, anomalía del prepucio dorsal y punta del pene roma. La valoración de la uretra durante la micción y el aspecto del chorro miccional son de gran utilidad para clasificar el defecto. Cuando se diagnostica hipospadias peneano o escrotal es aconsejable realizar una amniocentesis para estudio genético fetal y valorar otros signos de adecuada virilización, como el descenso testicular a partir de la semana 27. El seguimiento tras el parto debe ser multidisciplinario, incluyendo urólogo y endocrinólogo infantil. En hipospadias leves el pronóstico es bueno con reparación quirúrgica en el primer año de vida, pero las formas graves pueden presentar un reto mayor para su corrección funcional y estética.

Hypospadias refers to the abnormal location of the meatus; it is the most common genital malformation detected in the fetus and newborn. Prenatal diagnosis is feasible from 20 weeks onwards with routine ultrasound; however, it is easier to diagnose during the third trimester of pregnancy. Mild defects are usually isolated, familiar o related to placental disfunction or intrauterine growth restriction, while the severe hypospadias are associated to other fetal defects, genetic or chromosomal abnormalities or disorders of sex development. In about 30% of cases. The triad of ultrasound findings prenatally is ventral curvature of the penis, redundant dorsal foreskin and blunt distal penis. The identification of the urethra during the micturition and the direction of the urinary stream help in the classification of the defect. When severe hypospadias is detected, the recommendation is to perform genetic amniocentesis and search for other ultrasound findings related to poor virilization in the fetus, as testicular descent after 27 weeks of gestation. Postnatal follow up should be multidisciplinary including infantile urologist and endocrinologist. The prognosis in distal hypospadias is usually good following surgical repair, however in severe cases surgical interventions may be more challenging in order to obtain satisfactory outcome in terms of function and esthetic.

Infecciones Respiratorias Virales y la Placenta / Respiratory viral infections and the placenta

Las enfermedades infecciosas que comprometen el aparato respiratorio, generalmente son más graves en las gestantes y en las puérperas en comparación con las no embarazadas. Dentro de estas infecciones, se encuentran las producidas por agentes virales como la influenza estacional, pandémica y zoonótica, los coronavirus SARS, el MERS; y desde el año 2019 el SARS-CoV-2 causante de la actual pandemia COVID-19. Las noxas virales pueden ejercer un efecto deletéreo sobre el feto debido a respuesta inflamatoria vía cascada de citoquinas o daño directo a nivel de algunos tejidos. Los efectos del SARS-CoV-2 a nivel placentario, no están bien entendidos, los hallazgos histopatológicos incluyen alteraciones de la perfusión venosa materna y fetal y signos de inflamación placentaria en diferentes porcentajes. La placenta es un órgano altamente especializado que confiere una protección especial generando un ambiente protegido manteniendo un equilibrio de factores inmunes y bioquímicos que favorecen el desarrollo fetal. Su estructura funciona como una barrera protectora dificultando o impidiendo el paso de noxas al producto de la gestación. Diversos patógenos, incluyendo los virus pueden alterar los diferentes componentes celulares de la placenta. En la siguiente revisión describimos los más recientes hallazgos de la interacción con la placenta de diversos virus respiratorios y sus consecuencias en la salud materno fetal(AU)

Infectious diseases of the respiratory system generally present greater severity in women during pregnancy or puerperium, than in non-pregnant women. Among them, we find those produced by viral agents such as seasonal, pandemic and zoonotic influenza, SARS coronaviruses, MERS; and since 2019 the SARS-CoV-2, the cause of the current COVID-19 pandemic. Viral noxae can exert a deleterious effect on the fetus due to an inflammatory response via the cytokines cascade or direct damage at some tissues. The effects of SARS-CoV-2 on the placenta is not well understood, the histopathological findings include alterations of maternal and fetal perfusion and signs of placental inflammation in different degrees. The placenta is a highly specialized organ that confers a special protection by generating a protected environment maintaining a balance of immune and biochemical factors that favor the fetal development. Its structure works as a protective barrier, hindering or preventing the passage of noxae to the fetus. Several pathogens, including viruses, can alter different cellular components of the placenta. In the review, we describe the most recent findings of the interaction of various respiratory viruses with the placenta and their consequences on maternal and fetal health(AU)

Consenso de la COVID-19 en el embarazo / Consensus on COVID-19 in pregnancy

Después de un año de Pandemia por el virus SARS-CoV-2, causante de la COVID-19, la evidencia demuestra que las embarazadas son un grupo vulnerable a complicaciones durante toda la gestación, en el parto y el puerperio. Aunque el riesgo de transmisión vertical es bajo, la COVID-19 en las embarazadas está asociada a mayor ingreso a la UTI, ventilación mecánica y muerte. En ausencia de un tratamiento específico, la detección temprana y las intervenciones oportunas pueden disminuir el riesgo potencial de complicaciones durante el embarazo. La presente revisión que incluye información epidemiológica, manifestaciones clínicas, diagnóstico y conducta en la embarazada y el recién nacido, y recomendación sobre vacunas, pretende establecer un aporte al equipo de salud que atiende embarazadas y neonatos, para disminuir la morbilidad y mortalidad materno fetal asociada a la COVID-19. (AU)

After one year of the Pandemic caused by SARS-CoV-2, virus that causes COVID-19, the evidence shows that pregnant women are a group especially vulnerable to complications during the entire gestation, childbirth andpuerperium. Although the risk of vertical transmission is low, COVID-19 in pregnant women is associated with greater admission to the ICU, mechanical ventilation and death. In the absence of specific treatment, early detection and timely interventions can decrease the potential risk of complications during pregnancy. This review, which includes epidemiological information, clinical manifestations and behavior in pregnant women and newborns, aims to establish a contribution to the health team that cares for pregnant women and newborns to reduce maternal-fetal morbidity and mortality associated with COVID-19.

Variación del perfil lipídico durante el embarazo y su relación con las enfermedades metabólicas / Changes in lipid profile during pregnancy and their association with metabolic disorders

Introducción: En el embarazo se producen numerosos cambios fisiológicos en las gestantes los cuales pueden llegar a desencadenar potenciales complicaciones y enfermedades cardiovasculares o metabólicas tales como hipertensión gestacional, hiperlipidemia y diabetes mellitus gestacional.Objetivo: Realizar una revisión sistemática de la literatura con objeto de evaluar la relación entre las variaciones del perfil lipídico durante el embarazo y el riesgo de padecer enfermedades metabólicas y cardiovasculares.Métodos: Se ha llevado a cabo una revisión sistemática siguiendo las directrices del modelo PRISMA en la que se incluyeron 22 artículos. Los descriptores empleados incluyeron marcadores del perfil lipídico (HDL, LDL, TG y CT) y las principales patologías metabólicas y cardiovasculares. El idioma se restringió a español e inglés. La revisión fue llevada a cabo durante el año 2019.Resultados: Niveles elevados de colesterol total, LDL y triglicéridos durante el embarazo se asocian con un mayor riesgo de padecer preeclampsia y diabetes mellitus gestacional. Un mayor índice de masa corporal pre gestacional y una mayor ganancia ponderal se relacionan con mayor tasa hiperlipidemia lo cual conlleva a su vez alteraciones vasculares.Conclusiones: Se hace patente la necesidad de reforzar el control preventivo del peso materno trimestral y del perfil lipídico durante la gestación con objeto de prevenir complicaciones del embarazo. Son necesarios estudios centrados en determinados resultados adversos perinatales tales como la macrosomía del recién nacido.(AU)

Background: Various changes occur during pregnancy that, when exacerbated, could progress to metabolic and cardiovascular disorders such as gestational hypertension, hyperlipidemia, and gestational diabetes mellitus.Objective: To conduct a systematic review of the literature that evaluates the association between changes in lipid profile during pregnancy and the risk of developing metabolic and cardiovascular disorders.Methods: We conducted a PRISMA systematic review of scientific databases. A total of 22 articles were finally included. Used search terms consisted of lipid profile biomarkers (HDL, LDL, triglycerides, total cholesterol) in combination with the most important metabolic and cardiovascular disorders. Language was restricted to Spanish and English. The review was conducted during 2019.Results: High levels of total cholesterol, LDL and triglycerides during pregnancy were found to be associated with increased risk of developing preeclampsia and gestational diabetes mellitus. Higher pre-gestational BMI and elevated gestational weight gain were associated with increase rates of hyperlipidemia which is closely related to vascular pathologies.Conclusions: Fostering routine control of maternal weight during all trimesters of gestation and monitoring the lipid profile throughout pregnancy is necessary to prevent pregnancy adverse outcomes. New studies focused on specific perinatal outcomes such as neonatal macrosomia are required.(AU)

Effects of physical activity on quality of life in overweight and obese children / Efectos de la actividad física sobre la calidad de vida en niños con sobrepeso y obesidad

Background: in recent years the prevalence of obesity in infants, children, and adolescents has increased alarmingly, which may affect their health, educational level, and quality of life. Objectives: the aim of this study was to determine whether a program with physical activity and nutritional recommendations may improve health-related quality of life (HRQL) in overweight and obese children. Material and methods: the design of this study was that of a randomized clinical trial (RCT). The sample consisted of 54 children with a median age of 10.65 years, all of them overweight or obese. They were divided into a study (SG) and a control (CG) group, with 27 children each. The study group received physical activity and nutritional advice, while the control group only received theoretical-practical sessions on nutrition during 9 months. Families participated in the workshops on nutritional recommendations in both groups. Results: there was a significant difference in fat percentage before and after the intervention in the study group compared to the children who did not engage in sports activity. In the SF-10 quality-of-life perception questionnaire, statistically significant differences in both the physical and mental components may be seen at the end of the study between both groups (p < 0.001). Conclusions: an educational intervention with physical activity based on play and nutritional advice improved quality of life in overweight and obese children. Family involvement is vital for children to improve their life habits, and achieve favorable results in the reduction of overweight and obesity. (AU)

The COVID-19 pandemic lasting more than 1 year is a risk for many vulnerable groups already identified with epidemiological studies highlighting people over the age of 65, people with obesity-like comorbidities, diabetes hypertension, cardiovascular disease and immunosuppressants. Statistics of the COVID-19 pandemic in the general population and pregnant women are reviewed, with special revision of the Americas and Venezuela region. Pregnant women have been studied during the pandemic and it is concluded that it is a population at risk more vulnerable to complications during pregnancy, childbirth, postpartum and its product during neonatal life increased risk of serious illness and intensive care. Research groups are encouraged to join international monitoring protocols, and further study COVID-19 in pregnant women and fetuses.

Conocimientos de los trabajadores de la salud sobre aspectos generales de la COVID-19

El surgimiento del SARS-CoV-2 conllevó en sus inicios al tratamiento de las consecuencias, mucho antes de saber la forma de propagación y contención; el Trabajador de Salud (TS) constituye una población de alto riesgo para adquirir la enfermedad. Se buscó determinar el conocimiento de los TS sobre aspectos generales de la COVID-19. Es un estudio descriptivo, exploratorio, transversal. Se investigó el conocimiento sobre la COVID-19 en TS, del 15 al 22/4/2020, a través de una encuesta en línea con diferentes variables relacionados con el SARS-CoV-2. De 617 participantes hubo diferencia de hasta 9 números en las respuestas. Hubo una relación 2:1 de mujeres/hombres; 33.8 % se encontraban entre 51-60 años y el 78,2 % estaban residenciados en Venezuela. De 608 TS, el 25,5 % eran Gineco-Obstetras. Los encuestados demostraron conocimientos asertivos sobre el virus SARS-CoV-2, sobre el origen y período de incubación, y se observaron diferencias en las formas de transmisión y manifestaciones clínicas atípicas. Se concluyó que identificar las fortalezas y debilidades ante cualquier patógeno permite implementar nuevas acciones preventivas, elaborar estrategias educativas y comunicacionales con la finalidad de realizar conductas médicas adecuadas.

The emergence of SARS-CoV-2 initially led to the treatment of the consequences, long before knowing the form of spread and containment; The Health Worker (TS) constitutes a population at high risk for acquiring the disease. It was sought to determine the knowledge of the TS on general aspects of COVID-19. It is a descriptive, exploratory, cross-sectional study. Knowledge about COVID-19 in TS was investigated, from April 15 to 22, 2020, through an online survey with different variables related to SARS-CoV-2. Of 617 participants there was a difference of up to 9 numbers in the answers. There was a 2: 1 ratio of women / men; 33.8 % were between 51-60 years old and 78.2 % were resident in Venezuela. Of 608 TS, 25.5 % were OB / GYN. Respondents demonstrated assertive knowledge about the SARS-CoV-2 virus, its origin and incubation period, and differences were observed in the forms of transmission and atypical clinical manifestations. It was concluded that identifying the strengths and weaknesses in the face of any pathogen allows the implementation of new preventive actions, the elaboration of educational and communication strategies in order to carry out appropriate medical behaviors.

Alteraciones y efectos del sueño durante el embarazo / Sleep disorders during pregnancy

INTRODUCCIÓN: El embarazo es un proceso fisiológico que produce alteraciones en los patrones del sueño. A nivel fisiológico la falta de sueño se relaciona con problemas de salud tales como hipertensión, enfermedad coronaria, diabetes y depresión. En el embarazo, las alteraciones del sueño son más frecuentes siendo su prevalencia mayor durante el tercer trimestre. La deprivación del mismo durante el embarazo empeora significantemente las condiciones preexistentes de la mujer disminuyendo la actividad física diaria, la productividad y aumentando los síntomas relacionados con el estrés. Las alteraciones del sueño en el embarazo se pueden relacionar con comorbilidad en el recién nacido y resultados adversos materno-fetales. OBJETIVOS: Determinar qué alteraciones del sueño ocurren durante el embarazo, cuáles son sus causas y qué posibles consecuencias podría tener el déficit de sueño durante la gestación a nivel materno-fetal y neonatal. METODOLOGÍA: Se llevó a cabo una revisión sistemática siguiendo los principios de la declaración PRISMA. Se recogieron tanto estudios observacionales como de intervención así como revisiones sistemáticas y meta-análisis y se llevó a cabo un análisis crítico de los resultados. RESULTADOS Y DISCUSIÓN: Se incluyeron finalmente un total de 19 artículos que trataban sobre los efectos de las alteraciones del sueño en los resultados materno-fetales y neonatales y sus causas. Las principales causas de las alteraciones del sueño son los cambios hormonales y fisiológicos propios del embarazo como es el aumento de peso que se hacen más prevalentes conforme progresa la gestación. Las consecuencias maternas engloban principalmente trastornos respiratorios, alteraciones cardiovasculares e inflamatorias y resultados adversos del embarazo como es la cesárea. Los resultados adversos en el recién nacido más estudiados son partos prematuros y recién nacidos con bajo peso para la edad gestacional. CONCLUSIÓN: Con este trabajo se observa que existe una relación entre los trastornos del sueño durante el embarazo y los problemas materno-fetales. Sin embargo, los estudios llevados a cabo hasta la fecha son heterogéneos, emplean herramientas subjetivas y sus conclusiones resultan en ocasiones contradictorias

INTRODUCTION: Pregnancy is a physiologic stage of the women that modifies sleep patterns. Sleep deprivation is associated with pathologies namely hypertensive disorders, coronary artery disease, diabetes and depression. Amongst pregnant women sleep disorders are more frequent being its prevalence higher during the third trimester of gestation. Furthermore, sleep deprivation worsens previous conditions such as low degree of physical activity, productivity and increases stress-related symptoms. Sleep disorders could be associated with comorbidities in the newborn as well as pregnancy/perinatal adverse outcomes. OBJECTIVES: To determine which sleep disorders are associated with pregnancy, their causes and the potential effects that sleep deprivation could exert on pregnancy outcomes and the newborn. METHODOLOGY: We conducted a systematic review following the PRISMA statement. Observational, interventional and systematic reviews/meta-analyses were included and a critical analysis of the results was performed. RESULTS AND DISCUSSION: 19 papers about sleep disorders and pregnancy/perinatal outcomes were finally included. Mains causes of sleep disorders during pregnancy consisted of hormonal changes and weight gain which are more prevalent as gestation progresses.
